Self-praise and arrogance
The Prophet (sal Allahu alaihi wa sallam) said, “While a man was walking, dressed in clothes admiring himself, his hair combed, walking haughtily when Allah caused the earth to swallow him. Now he will continue to go down in it (as a punishment) until the Day of Resurrection.”
Allah says (interpretation of the meaning): “And walk not on earth with conceit and arrogance.” (al-Israa 17: 37)
“And turn not your face away from men with pride, nor walk in insolence through the earth. Verily, Allah likes not any arrogant boaster.” (Luqman 31: 18)
The above Hadith warns us against self-praise and arrogance which may pervade our hearts by fine clothes and physical beauty.
Instead of adopting a proud attitude, we should be sensible enough to thank Allah for these favours and confess our servitude to Him.
Allah in the Quran tell us about the story Qarun (Korah), Allah says (interpretation of the meaning):
“Verily, Qarun (Korah) was of Musa’s (Moses) people, but he behaved arrogantly towards them. And We gave him of the treasures, that of which the keys would have been a burden to a body of strong men. Remember when his people said to him: ‘Do not exult (with riches, being ungrateful to Allah). Verily, Allah likes not those who exult (with riches, being ungrateful to Allah…(up to)… So We caused the earth to swallow him and his dwelling place.” (al-Qasas 28: 76-81)
And Allah knows best!
